What is the process to upgrade SQL 2005 service packs in a DR configuration?


Solution



The following is the upgrade procedure:
1. Stop replication between primary and secondary by VEA.
2. Upgrade secondary from SQL2005SP3 to SQL2005SP4, using passive mode. Reboot if is required.
3. Upgrade the passive node of primary site to SQL2005SP4, using passive mode. Reboot if is required.
4. Upgrade the active node of primary site to SQL2005SP4, using active mode. Reboot if is required.
5. Resume replication.

Frequently asked questions:

     This is a recommendation for best practices, but nor required.


2. Is it correct to consider all nodes of secondary site as passive?

          2. All passive nodes on primary
